[MR-guided ultrasound surgery]

JÓLESZ Ferenc A., BÉRCZI Viktor, HÜTTL Kálmán, REPA Imre, HYNYNEN Kullervo

[The powerful union of focused ultrasound surgery and magnetic resonance imaging has created a new approach to noninvasive surgery. Using this integrated therapy delivery system the physician can achieve correct localisation of tumors, optimal targeting of acoustic energy, real time monitoring of energy deposition, and the means to accurately control the deposited thermal dose within the entire tumor volume. The advantages of MRI over ultrasound guidance in controlling focused ultrasound surgery lie in the more sensitive detection of tumor target, the real time detection of tissue temperature, and the confirmation of thermally-induced tissue changes - powerful features that eventually can replace the traditional surgical approach. Applying software that connects the therapy and imaging system, the physician can generate an entire plan from quantifying temperature changes to positioning the therapy transducer. The non-invasive debulking of tumors without disturbing adjacent, functionally intact structures is thereby accomplished. Ongoing clinical trials involving the treatment of breast fibroadenoma, localized breast cancers, and uterine fibroids have been most encouraging. But nowhere has the application of MRI-guided focused ultrasound surgery been more compelling than in brain, where not only tumor treatment is possible but also the focal, transient, reversible breakdown of the blood-brain-barrier. The implications of this mechanism for targeted intra-cerebral tumor therapy or other non-oncologic applications are clearly enormous. In addition to tumor treatment, MRI-guided focused ultrasound surgery has other potential clinical applications such as vascular occlusion, targeted drug delivery, and targeted gene therapy. FUS is not a new idea but the emergence of MRI based guidance has accelerated the progres of focused ultrasound surgery technology, certain weaknesses remain including excessively long treatment times, body and organ motion, and difficulties in finding acoustic windows at certain anatomic locations. Nevertheless, the successful clinical implementations of this method is already in progress.]

[Antecedents to the commencement and history of the West- Pannonic neurological forum]

GARZULY Ferenc, GRUBITS János, NIKL János

[Introduction - Numerous professional groups and sections for the medical specialities have been organized since 1953 in the West-Transdanubian region of Hungary, but such association of neurologists had not occured. Establishing the West-Pannonic Neurological Forum - The lack of regional collaboration among neurologists was related to several factors, among which the most important factor was the lack of a regional medical university, which could coordinate the professional activities. This severe gap necessitated in 1998 the organization of a professional group, that has become a driver for case-consulting conferences and different postgraduate trainings for the physicians specialized in neurology, neurosurgery and neurorehabilitation in counties of Győr-Moson-Sopron, Vas, Veszprém and Zala. The functioning of the Forum - Meetings are organized twice a year for physicians and paramedical staff (nurses, hospital attendants, physiotherapists) on Thursdays afternoons in different towns of the region, in two sections. The lectures are followed by a buffet, after which everyone can get home before too late. Ocasionally guest-lecturers are invited to present scientific topics from Hungarian universities or abroad. However, the main form of the presentations is defined as case discussion. Conclusions - The numbers of platform and other presentations in the physicians’s section have exceeded half a thousand, while in the paramedical section reached the threehundreds. At the 38. meeting of the Forum in January of this year, the number of participants was more than twohundreds, reflecting that both physicians and their coworkers are greatly interested in this form of interactions.]

[Relationships in recovery, recovery in relationships]

SZABÓ József, GEREVICH József

[INTRODUCTION - Some of the recent researches based on analyses of autobiographies pointed out, that the quality and the quantity of our social relations are in connection with our life longevity, and the frequency of words referring social roles and integration gives a respective measurement possibility of it. Conception of the term “social words” had been introduced. The influence of the degree of social support to the recovery from alcohol addiction is also a well-known phenomenon. Based on the above we supposed that examining their autobiography vocabularies we find special differences which can show the distinction between the social support of the relapsed and recovering addicted persons. We planned to prove the being of these special differences via revealing bias of the frequency and pattern of social word usage. PATIENTS AND METHODS - Two separate groups were created for purpose of the examination. The first consisted of relapsed alcohol dependent persons, who were treated in hospital (department of addiction psychiatry) diagnosed alcohol-dependent (F 10.2) (and nothing else) at least twice within a year (N=30). We chose earlier treated (because of alcohol-dependency, and nothing else mental disease) persons who had been being abstinent for at least 2 years into the second group (N=20). Beside the earlier diagnosis we used the parts of the ASI test to sreen any other mental diseases. We created similar groups with regards to gender, age and qualification. We collected autobiographies from the persons, and made two common documents of them. Afterwards we compared these documents by the Atlas.ti 5.0 (trial free version) content analysing software. We defined the frequency of the found social words in the rate of these words and the sum of the words in the whole text. We found the most prominent difference between the frequency of social words referring to the family and relatives, opposite the words dealing with friendship. RESULTS - In the latter case we could not detect any difference between the two groups. We got results confirming our hypothesis in the frequency of such words as “help”, “love”, “give” and “get”. We experienced in connection with the pattern that the words referring to social organisations, for example “team”, “community”, “company”, “club”, “meeting”, “collective” and the word “guest” practically did not appear (R<0.001) in the texts of relapsed persons, while they could be detected in the case of the recovering group (R=0.023). We did khisquare test to compare the frequency in the mentioned categories and we experienced significant differences between the social word usage of the two groups. CONCLUSION - Our results confirmed that the recovery from alcohol addiction was related to the quality and quantity of person's social relations, what we can get relevant information from the frequency of social words in the autobiographies about, so the high frequency of the social words can be considered as a good predictor of recovery.]
